Some Detail about harmonic gear

But then I've extended the planets and sun gears and added an additional flexible gear with 93 teeth, essentially creating a harmonic drive. The overall reduction 155:1. It's no surprise that the estimable emmett has also designed a hybrid...

4th version of my strain vawe drive. ...Its design is very sturdy and, depending on a motor, very powerful. If you have any question about the gear drive feel free to ask me.

"Diferential Harmonic Reducer Case v1.3mf", "Diferential Harmonic Reducer eliptical BB n spline v1m.3mf", and "Harmonic V1 demo handle.stl" The flex spline has a small notch on the top side, this goes "up" when inserted into the large case half. Be...

Please take a look at the included Report and video for a more exaustive explanation of this entry.In summary:This is a modified 2 stage harmonic transmission, there are no roller bearings, the friction reduction is obtained by coating all the mating...

Here's the plan to make my first mechanical computer : A Fourier series composer, made from lasercut frames and gears, a bunch of springs and a pen, to create sine waves and add them to draw a signal. Despite my terrible grades at my Fourier's...

A working educational model of a "Harmonic drive" also named a "strain wave gearing" using a 3/4" chain and some plexi. This one has a gear ratio 1/5. The chain counter-rotates in a wave form, almost moving like a serpent... it works rather strange...

Harmonic drives are mechanical gear systems that have some very nice properties such as no backlash, high gear ratios, and being able to hold their position without power : http://en.wikipedia.org/wiki/Harmonic_drive Harmonic drives have an...

harmonic drive i made, uses 7.9 mm steal ball bearings. ...make sure to split into parts before printing

A harmonic drive is a very simple gear reducer that lends itself well to 3D printing. It uses a rigid outer gear and an inner flex spline. The flex spline has a few less teeth (typically 2 less) than the outer gear. You stretch the flex spline so...

My goal was to implement the principle of the harmonic drive into a sturdy solid module that can ultimately be used for making a robotic arm. This is my first prototype, and it works quite nicely.http://youtu.be/D_neLbcW_BY The circular spline has 84...

It is a type of harmonic drive, which uses a flexible output ring to attain a high gear reduction. My design is unique (as far as I know) in that it also incorporates a planetary gearset for further reduction. Instead of a toothed belt for the...

This is a harmonic drive for a nema 17 stepper. You need a few parts to complete this. 4 M6 x 10 or 12mm long Button head cap screws. (wave generator) 4 x 606-2rs bearings (wave generator) 24 x M3 X 16mm Flat Head Cap Screws (at least 12) 4 x M3 X...

This is a tri-lobe harmonic drive (because why not ?) Here are the videos where I talk about it :https://www.youtube.com/watch?v=yehE7aFYUGUhttps://www.youtube.com/watch?v=ajxFor8MDcA Thing comes complete with its solidworks source. Also available on...

Since original harmonic drive gearings are too expensive for me (one costs about 600€) im trying to build my own version. Im using 6mm steel softair BBs for the flexible bearing inside of the gearing. I already printed an approx. model of the...

Undoubtedly there is something wonderful, if not magical, about harmonic drive gearing, also know as strain wave gearing. If you want gearing with high ratios and little backlash and a lightweight design, I guess there is no way around it. In this...

Simple telescope mount using two CSF-14 and two CSG25 harmonic drives. ...Uses Nema 23 stepper motors with encoders.A variety of gear reductions can be attained depending on the harmonic drive section.

Harmonic drive ratio- 1:100 (can be increased)Spur gear ratio 1:5This combination has much higher efficiency than combination of worm gears and multiple spur gearsDepending on the assembly requirement 3 spur gears can be used instead of 2 to open up...

There also is the 25 tooth GT2 belt that would be very difficult to source as it is not a normally stocked size.If you don’t quite understand the mechanics behind a Harmonic Drive, I recommend watching this video, it does a great job explaining the...
